Reposting the full series for review. Assuming this is all OK would it
be a good idea to merge the config variables into a single
CONFIG_ARCH_OMAP7XX? There doesn't seem to be any reason to have both.
Original description follows.
Hello from the Linwizard project,
We have been working on supporting omap850 smartphones from HTC such
as Wizard, Herald etc. We have found that omap730 and omap850 are
almost exactly the same. As far as what is supported in linux-omap so
far, they are identical. Currently there are seperate code paths for
730 and 850, and this is causing us a lot of problems when one is
changed and the other isn't. I also noticed that OMAP F-Sample board
uses ARCH_OMAP730 even though it has a OMAP850 SoC.
In order to try to clean this up I have produced a patch series which
removes all cpu_is_omap730/850 and replaces them with unified
cpu_is_omap7xx() blocks, and similarly merges CONFIG checks. Here is a
random example:
-#ifdef CONFIG_ARCH_OMAP730
- if (cpu_is_omap730()) {
+#if defined(CONFIG_ARCH_OMAP730) || defined(CONFIG_ARCH_OMAP850)
+ if (cpu_is_omap7xx()) {
irq_banks = omap730_irq_banks;
irq_bank_count = ARRAY_SIZE(omap730_irq_banks);
}
#endif
-#ifdef CONFIG_ARCH_OMAP850
- if (cpu_is_omap850()) {
- irq_banks = omap850_irq_banks;
- irq_bank_count = ARRAY_SIZE(omap850_irq_banks);
- }
-#endif
Drilling down through the variables shows they are always equivalent
for 730 and 850, except where there is a bug.
This makes several bugs go away for us on omap850, including the
MPUIO_VBASE bug, and the lack of working IRQs - since these bugs arn't
in the 730 paths. It would hopefully prevent similar bugs from showing
up in the future too.
